Spiruridae
Spiruridae is family of nematodes in the order Spirurida. An unidentified parasitic larval member of this family has been recorded in the marsh rice rat (''Oryzomys palustris'') in a salt marsh at Cedar Key, Florida, and also in fiddler crab The fiddler crab or calling crab may be any of more than one hundred species of semiterrestrial marine crabs in the family Ocypodidae, well known for their sexually dimorphic claws; the males' major claw is much larger than the minor claw, while ...s (''Uca'') there; it is perhaps a bird parasite that does not reach maturity in the rice rat.Kinsella, 1988, p. 278 See also * List of parasites of the marsh rice rat References Literature cited *Kinsella, J.M. 1988.

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant- parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time.

List Of Parasites Of The Marsh Rice Rat
A variety of parasites have been recorded from the marsh rice rat (''Oryzomys palustris''), a semiaquatic rodent found in the eastern and southern United States, north to New Jersey and Kansas and south to Florida and Texas, and in Tamaulipas, far northeastern Mexico. Some of these parasites are endoparasites, internal parasites, while others are ectoparasites, external parasites. Parasitologist John Kinsella compared the endoparasites of marsh rice rats in a saltwater marsh at Cedar Key and a freshwater marsh at Paynes Prairie, both in Florida, in a 1988 study. He found a total of 45 species, a number unequaled in rodents. This may be related to the diverse habitats the rice rat uses and to its omnivorous diet; it eats a variety of animals which may serve as intermediate hosts of various parasites. The endoparasites in the saltwater marsh were dominated by trematodes (flukes), and those of the freshwater marsh by nematodes (roundworms). Endoparasites were found in th ...

Spirurida
Spirurida is an order of spirurian nematodes. Like all nematodes, they have neither a circulatory nor a respiratory system. Some Spirurida, like the genus '' Gongylonema'', can cause disease in humans. One such disease is a skin infection with Spirurida larvae, called " creeping disease". Some species are known as eyeworms and infect the orbital cavity of animal hosts. Systematics The Camallanida are sometimes included herein as a suborder, and the Drilonematida are sometimes placed here as a superfamily. There are doubts about the internal systematics of the Spirurida, and some groups placed herein might belong to other spirurian or even secernentean lineages.ToL (2002) The following superfamilies are at least provisionally placed in the Spirurida: * Acuarioidea * Aproctoidea * Diplotriaenoidea * Filarioidea * Gnathostomatoidea * Habronematoidea Habronematoidea is a superfamily of spirurian nematodes in the large order Spirurida.

Marsh Rice Rat
The marsh rice rat (''Oryzomys palustris'') is a semiaquatic North American rodent in the family Cricetidae. It usually occurs in wetland habitats, such as swamps and salt marshes. It is found mostly in the eastern and southern United States, from New Jersey and Kansas south to Florida and northeasternmost Tamaulipas, Mexico; its range previously extended further west and north, where it may have been a commensal in corn-cultivating communities. Weighing about , the marsh rice rat is a medium-sized rodent that resembles the common black and brown rat. The upperparts are generally gray-brown, but are reddish in many Florida populations. The feet show several specializations for life in the water. The skull is large and flattened, and is short at the front. John Bachman discovered the marsh rice rat in 1816, and it was formally described in 1837. Several subspecies have been described since the 1890s, mainly from Florida, but disagreement exists over their validity. The Florida Key ...

Cedar Key, Florida
Cedar Key is a city in Levy County, Florida, United States. The population was 702 at the 2010 census. The Cedar Keys are a cluster of islands near the mainland. Most of the developed area of the city has been on Way Key since the end of the 19th century. The Cedar Keys are named for the eastern red cedar ''Juniperus virginiana'', once abundant in the area. History Early While evidence suggests human occupation as far back as 500 BC, the first maps of the area date to 1542, when it was labeled "Las Islas Sabines" by a Spanish cartographer. An archaeological dig at Shell Mound, north of Cedar Key, found artifacts dating back to 500 BC in the top of the mound. The only ancient burial found in Cedar Key was a 2,000-year-old skeleton found in 1999. Arrow heads and spear points dating from the Paleo period (12,000 years old) were collected by Cedar Key historian St. Clair Whitman and are displayed at the Cedar Key Museum State Park. Followers of William Augustus Bowles, self-dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiddler Crab
The fiddler crab or calling crab may be any of more than one hundred species of semiterrestrial marine crabs in the family Ocypodidae, well known for their sexually dimorphic claws; the males' major claw is much larger than the minor claw, while the females' claws are both the same size. A smaller number of ghost crab and mangrove crab species are also found in the family Ocypodidae. This entire group is composed of small crabs, the largest being slightly over two inches (5 cm) across. Fiddler crabs are found along sea beaches and brackish intertidal mud flats, lagoons, swamps, and various other types of brackish or salt-water wetlands. Like all crabs, fiddler crabs shed their shells as they grow. If they have lost legs or claws during their present growth cycle, a new one will be present when they molt. If the large fiddle claw is lost, males will develop one on the same side after their next molt. Newly molted crabs are very vulnerable because of their soft shells. They a ...
